Notification Appliances—PS12/24ADA Series Signaling Strobe and Sounder 3
Introduction
This document contains important information about installing and
operating PS12/24ADA series signaling strobes and piezo electronic
sounders. These strobes and sounder/strobes are manufactured by System
Sensor for use with Johnson Controls systems. The strobes are UL 1971
Listed for signaling devices for the hearing impaired. Those models that
produce 75 candela (cd) meet the Americans with Disabilities Act (ADA)
light output requirements of 75 cd on axis. Those strobes that produce less
than 75 candela may be considered as meeting ADA equivalency
requirements when applied per the National Fire Protection Association
National Fire Code Standard (NFPA-72) and with the approval of the local
authority having jurisdiction.
These instructions apply to the entire PS12/24ADA series signaling
strobes and sounders. Follow only those instructions that apply to the
model you are installing. If you install this strobe for someone else to use,
you must leave a copy of this document with the user.
Before you install any PS12/24ADA series signaling strobes and sounders,
read and be familiar with:
●the control panel system installation manual
●the requirements of the authority having jurisdiction
●National Fire Protection Association
(NFPA)-72-National Fire Alarm Code
●System Sensor Strobe Compliance Reference Guide, which provides
detailed information on strobe spacing, placement, zoning, and ADA
requirements
●or, for non-United States installations, applicable codes and standards
specific to the country and locality of installation
Failure to follow these directions may result in failure of the device to
report an alarm or trouble condition. Johnson Controls is not responsible
for devices that have been improperly installed, tested, or maintained
by others.
As is the case with all installations under NFPA, Underwriters
Laboratories, Inc. (UL), Underwriters Laboratories of Canada (ULC), or
Canadian Electrical Code classification, final written approval of
permissible operation and configuration rests with the authority having
jurisdiction.

!
CAUTION: Equipment hazard. Do not use in potentially
explosive atmospheres. Do not leave unused
wires exposed.
The piezo electronic sounder and signaling strobe are intended to be
connected to the alarm indicating circuit of a UL Listed fire alarm control
panel. Both sounder and strobe are compatible with DC line supervision.
The electronic sounder can be connected to either 12 or 24 VDC panels.
The strobes produce one flash per second (nominal) with continuous
nominal voltage applied.
Note: The strobe cannot operate from coded power supplies, which
produce interrupted power. The strobe must have an uninterrupted
source of power in order to operate correctly.

UL 1971 requires a polar light distribution pattern to enhance the
likelihood of alerting hearing impaired individuals throughout an area.

All models can be powered using Full-Wave Rectified (FWR), unfiltered
(unregulated) power supplies. However, if the power supply is
unregulated, the notification appliance must be compatibility listed for use
with the fire alarm system. If the power supplied is from a regulated
power supply, no compatibility listing is required. In addition, follow the
guidelines listed below:
●Under no circumstances can PS24ADA series devices input voltage
exceed 33 VDC or be less than 16 VDC peak when using a regulated
power supply. When using an unregulated power supply, the range is
16-33 VRMS.
●Under no circumstances can a PS12ADA or MASS12ADA series
device input voltage exceed 18.7 VDC or be less than 8.5 VDC for a
regulated power supply. When using an unregulated power supply,
the range is 8.5-18.7 VRMS.

Note: Inrush current duration is less than 20 microseconds (0.00002 seconds).
Note: Inrush current refers to current that exceeds the peak current when
the strobe is first turned on. Once the strobe is turned on, it flashes
one flash per second. Peak current indicates the current rising
above the average operating current right after each strobe flash.

Installation Procedures
This section contains installation information for PS12/24ADA series
strobes and sounder/strobes. Mounting instructions and wiring
information are provided.
Installation procedures must conform to all applicable codes and the
requirements of the authority having jurisdiction.
For strobe placement, read and be familiar with:
●NFPA 72-National Fire Alarm Code
Both slotted-head and Phillips-head screws are supplied with the
speaker/strobe.
●Use the slotted-head screws to mount the semi-flush plate to the
electrical box.
●Use the Phillips-head screws to attach the PS12/24ADA to a
semi-flush plate or to the electrical backbox.
Note: The rated output of the sounder is specified at ten feet on axis.
It cannot be assumed that the output will meet the NFPA standard
of 15 dB over ambient noise at all locations within a room.
Additional sounders may be needed to ensure that the sound output
level complies with NFPA requirements.
Strobe and sounder/strobe combination are designed for wall mounting
only. The PS12/24ADA is intended for mounting to a standard 2-1/2 inch
deep single gang box which allows for sufficient clearance for conduit
entrance.
All strobes must be mounted where the top of the lens is 24 inches below
ceilings or as required by the authority having jurisdiction.
For mounting the sounder/strobe, note the following figures:
●Surface Mount (Figure 2)
●Semi-flush Mount (Figures 3 and 4)
●Semi-flush Mount with Plaster Ring or Double Gang Box (Figure 5)
